I agree call brewers they will tell you what you need. I'm pretty sure the drive shaft length is the same (do you have a broadcast sheet for you car? there is a number on it for drive shaft and could be compared to a 4spd car. The slip yoke may be different. If you get a Ebody 4spd with a shifter and linkage you should be good to go. Make sure the input spline is the same most likely a 23 spline. I need a drive shaft for a 70 cuda 3spd so if you don't use yours let me know. I live in CT also.
